Innovation Solution
A remote operation device and system that includes a first operation unit for forward and backward movement, with a control unit capable of wirelessly transmitting command signals to the transport vehicle to move precise distances, and an adjustment mechanism for fine-tuning these distances based on user input and weight measurements, ensuring accurate alignment with a target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous control is used for transport vehicle, then productivity is improved, but alignment precision deteriorates
Solution Approach 1:
The control system is segmented into autonomous control unit and remote operation unit. The autonomous control handles routine navigation and movement to maintain productivity, while the remote operation unit takes over specifically for precision alignment tasks at work positions, combining the advantages of both automated efficiency and manual precision
Solution Approach 2:
A remote operation device acts as an intermediary between the autonomous transport vehicle and the operator. This intermediary allows the vehicle to operate autonomously for most tasks while enabling precise remote intervention when alignment accuracy is required, resolving the contradiction between autonomous productivity and precision alignment
2Manufacturing precision
If remote operation is implemented, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The remote operation device is designed with multi-functionality, serving as a universal control interface that can operate the transport vehicle for both navigation and precision alignment tasks. This consolidates multiple control functions into a single device, improving alignment precision without proportionally increasing overall system complexity
Solution Approach 2:
The transport vehicle is equipped with self-positioning capabilities and autonomous navigation systems that handle routine operations independently. The remote operation system only activates when precision alignment is needed, allowing the system to serve itself for most tasks while reducing the burden on the remote operator, thereby improving alignment precision without excessive complexity increase
